A list of fishes collected in the vicinity of Kikwit on the Kwilu River, a large left bank tributary of the Kasai River in the Democratic Republic of Congo is provided. One hundred and thirteen species distributed in 21 families are reported, and of these 29 species are recognized as representing new records for the region. Lack of up-to-date taxonomic and distributional knowledge of African fishes, a problem particularly acute in the central Congo basin, is clearly reflected in this high number of range extensions. While preliminary, this contribution serves as a useful starting point for efforts to understand the ichthyofaunal composition and biogeographic history of the Kasai system; one of the most poorly documented river systems in central Africa.

Current Report

A list of fishes collected in the N’sele River, a large affluent tributary of Pool Malebo, in the Democratic Republic of Congo is provided. Sites along the main channel and its affluent tributaries were sampled and 148 species distributed in 27 families are reported. Despite close proximity to the megacity of Kinshasa, the ichthyofauna of the N’sele River has not previously been documented, and in the course of the current study, 19 of the 148 species are recognized as new records for the region. Due to difficulties of access much of the middle reach of the N’sele River remains to be inventoried and, while the present report documents high diversity in this system, the list is likely to be incomplete. Although preliminary, the current report provides a solid foundation for further work in a region that is undergoing rapid environmental degradation.

Rare And Endangered

A list of fishes collected in and around the periphery of the Salonga National Park in Equateur Province of the Democratic Republic of Congo is provided. While noteworthy for a wide array of rare and endangered terrestrial vertebrates, the fish fauna of the Salonga National Park, the largest protected area in Africa, is very poorly known. One hundred and fifty two species distributed in 24 families are reported on here; of which 9 represent putatively undescribed taxa currently under investigation. Lack of up-to-date taxonomic and distributional knowledge of African fishes is particularly acute in the central Congo basin and the present report, while undoubtedly incomplete, provides a foundation for much needed further work in the region.

Constitutional Factor

Constitutions around Africa have been repeatedly tested on the issue of presidential term limits. We explore the four most recent cases of African presidents facing the end of their constitutionally mandated limit, all of which developed in Central Africa. Burundi, Rwanda, the Republic of Congo, and the Democratic Republic of Congo all adopted constitutions limiting presidential tenure to two terms; yet, in 2015, when these limits were approaching, none of the sitting presidents simply stood down. Our analysis focuses on the constitutional provisions meant to protect the two-term limit, the strategies employed by each of the four presidents, and the difficulty they faced in pursuing extended tenure. We find that constitutional provisions do constrain, but not always to the expected degree. Our analysis adds a consideration of a foundational constitutional factor to the growing literature on term limits in Africa, with implications for other regions of newly developing democracies.

Abstract Background Recent studies suggest a measles-induced immune amnesia that could have long-term immunosuppressive effects via preferential depletion of memory B and T CD150+ lymphocytes. Methods We examined the association between past measles and tetanus antibody levels among children participating in the 2013–2014 Democratic Republic of Congo (DRC) Demographic and Health Survey (DHS). Our sample consisted of 833 children aged 6–59 months whose mothers were selected for interview. Mothers reported (via recall) history of measles within the lifetime of the child. Classification of children who previously had measles was completed using maternal recall and measles immunoglobulin G (IgG) serostatus obtained via dried blood spot (DBS) analysis. A multiplex chemiluminescent immunoassay platform was used to obtain serologic results and Assay Score (AS) was calculated as a ratio to a positive control included in each run. Tetanus serostatus was categorized as being above or below the sample median serology AS value. Tetanus vaccination status was obtained via dated vaccination card and limited to children receiving the complete 3-dose vaccination series. Results The median AS for tetanus serology among the entire sample of 833 children was 0.085, while children with history of measles had a median AS of 0.053 (N = 41) and children with no history of measles had a median AS of 0.088 (N = 792), chi-square P-value < 0.05. A random intercept logistic regression model was used to examine the association between previous measles disease and odds of having below median levels of tetanus antibody. Controlling for potential confounding variables, the odds of a child with past history of measles having less than the median level of tetanus antibody was 3.86 (95% CI: 1.70, 8.78) among children fully vaccinated for tetanus. Conclusion The results suggest that, among children 6–59 months in DRC, measles may have a long-term impact on levels of pre-existing, vaccine-induced immunity to tetanus. These findings suggest the need for laboratory studies examining measles’ impact on pre-existing, vaccine-induced immunity and underscore the need for continued evaluation and improvement of DRC’s measles vaccination program.

Brown Streak

Cassava plays a key role in assuring food security and generating income for smallholder farmers throughout central Africa, and particularly in the Democratic Republic of Congo (DRC). This status is threatened, however, by cassava brown streak disease (CBSD) which has recently expanded its incidence and range in eastern DRC. The study described here, comprises the first extensive assessment of temporal change in occurrence of CBSD and its causal viruses in DRC, based on surveys conducted during 2016 and 2018. Cassava fields were inspected in Ituri, Nord-Kivu, Sud-Kivu, Tanganyika and Haut-Katanga provinces within eastern DRC, to record foliar incidence and severity of CBSD. Leaf samples were collected for virus detection and species-level identification. New occurrences of CBSD, confirmed by virus diagnostic tests, were recorded in two provinces (Haut-Katanga and Sud-Kivu) and nine previously unaffected territories, covering an area of > 62,000 km2, and at up to 900 km from locations of previously published reports of CBSD in DRC. Overall, average CBSD incidence within fields was 13.2% in 2016 and 16.1% in 2018. In the new spread zone of Haut-Katanga, incidence increased from 1.7% to 15.9%. CBSD is now present in provinces covering 321,000 km2 which is approximately 14% of the total area of DRC. This represents a major expansion of the CBSD epidemic, which was only recorded from one province (Nord-Kivu) in 2012. Both cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV) were detected in Ituri, Nord-Kivu and Sud-Kivu, but only CBSV was detected in Haut-Katanga. Considered overall, these results confirm the increasing threat that CBSD poses to cassava production in DRC and describe an important expansion in the African pandemic of CBSD.
